Of course it’s always best if you start with a raw image, but you can open a JPEG image in Adobe Camera Raw and get the same effect. Assuming the camera didn’t throw out too much necessary detail when creating the jpg, of course. Thanks for the great tutorial!

Russell Brown has created the BEST TRAINING VIDEO OF THE DECADE! Even if you don’t plan to use his specific effect, seeing the range of possibilities out of RAW is incredibly valuable. Most videos — understandably — are trying to make it look “right.” In that most are alike! But Mr. Brown spreads his wings and soars with his parrot over mountains, Asian gardens and more. Beautiful. More!
